| 8 | The <b>BOOST_PP_ARRAY_POP_BACK</b> macro pops an element from the end of an <i>array</i>. | |
| 9 | </div> | |
| 10 | <h4>Usage</h4> | |
| 11 | <div class="code"> | |
| 12 | <b>BOOST_PP_ARRAY_POP_BACK</b>(<i>array</i>) | |
| 13 | </div> | |
| 14 | <h4>Arguments</h4> | |
| 15 | <dl> | |
| 16 | <dt>array</dt> | |
| 17 | <dd> | |
| 18 | The <i>array</i> to pop an element from. | |
| 19 | </dd> | |
| 20 | </dl> | |
| 21 | <h4>Remarks</h4> | |
| 22 | <div> | |
| 23 | This macro returns <i>array</i> after removing the last element. | |
| 24 | If <i>array</i> has no elements, the result of applying this macro is undefined. | |
| 25 | </div> | |
| 26 | <div> | |
| 27 | This macro uses <b>BOOST_PP_REPEAT</b> internally. | |
| 28 | Therefore, to use the <i>z</i> parameter passed from other macros that use | |
| 29 | <b>BOOST_PP_REPEAT</b>, see <b>BOOST_PP_ARRAY_POP_BACK_Z</b> | |
